That's probably up to Canadians to decide. But there's quite a lot of space. ;). Joking aside, this sort of thing was done in the UK years ago. places like Milton Keynes, Crawley, Stevenage. Its not without its issues. and not a simple endeavour. But really, its laughable to someone living in a crowded country, that one of the most , in parts, sparsely populated countries in the world, isn't apparently looking into this. It'd be a 10-15 yr plan perhaps to implement. But with government commitment, the right tax incentives etc. Look how much China has built out in the last 20 yrs. Edit- cold winters are an issue in parts of Canada but climate change is actually opening up new areas, right?
